Heir to the Throne and IN
As of HTTT, the once viable strategy of declaring war on the Mongol Khanate won't work. If you do, the Ming Dynasty will only be too happy to pound you into the dirt because the Mongols are their vassals. Your best bet is to skip that step, and jump straight to Quest for the New World idea and make with the colonization then war with Tibet. After this, you'll still have a problem with manpower and money. None of the provinces you take will give you large amounts of either unless you go to war with Ming and manage to take some of their stuff.
Taking on the Ming
Do everything you can to convince them to give you military access. Send a few troops across the border and start counting the numbers of troops the Ming have near the border and take note of the larger contingencies. Once you have a rough idea on the forces you'll be facing bring your scouts back, cut your military funding to 50%, and start building up a respectable horde of cavalry and toss in a few infantry to lay siege to cities. Wait until the Ming are at war with one of their neighbors, raise military funding, and cancel your military access then declare war in the month that follows. Use your cavalry to cut down the smaller armies and start laying siege to the Qin provinces (the ones between your starting area and Tibet). Try to make a nuisance with the bulk of your cavalry further into China and try to draw some of the Ming armies to them rather than your smaller infantry forces. If you can get a general that has a high maneuver score, that helps tremendously since you'll be able to evade the legions of Ming soldiers that will come after you.
No matter what else happens, make sure you sue for peace before whoever else is fighting the Ming. If they sue for peace first and the Ming agree, you'll be facing the entire Ming army by yourself and they will be less inclined to agree to a peace that doesn't involve you giving up Tibet (and the 1200ish manpower it provides... this is a massive hit). If you time it right and you've had a bit of luck with your attacks, you might be able to talk the Ming into giving up a province and ending their vassalage of the Mongol Khanate. Worst-case scenario, try to make them give up the Khanate.
After the first Ming war, the Khanate should have good relations with you, insult them until they do not, then conquer them. This should give another 1500 manpower, which isn't a lot, but you'll need it. Do what you can to get your badboy down, and improve relations with other nations bordering the Ming. This will be a long and expensive undertaking, but you'll need them for future wars against the Ming. Manchu and Japan are good choices, and if any of the smaller nations in Indochina have managed to subjugate their neighbors sweet talk them as well. Form alliances with as many of them as you can. If you can only get one, go with Japan, with their naval inclination, they can cause havoc among the Ming and give your troops a chance.
For the next Ming war, same plan as before, minus the scouting bit, you won't be able to salvage relations with the Ming and still be able to convince Manchu and Japan to help. Stockpile your cavalry, be prepared to negotiate peace first. Take provinces, at least two. Rinse, lather, repeat. Depending on game specific circumstances and how well Ming will handle the rebels, they can be gone completely in a few centuries. After that, you're pretty free to do as you see fit, but you've only got the last half or so of the game left to do it. You could go to war with Manchu or try to expand towards India or Southeast Asia.
EU3 and NA
When playing as Oirat Horde you will have two problems, you have no allies and your relations with the neighbouring countries are terrible, so you are on your own. When you start: Send a merchant to Jiangsu; move your troops to the Mongol Khanate border. Wait a few months and declare war on Mongol Khanate. They are very easy to defeat, because they have no allies and only one army which they keep in their capital province. After the war recruit at least one advisor that gives you more colonists. Wait until you gain a government tech level. Choose "Quest for the New World" as a national idea and start colonising land to the north. You can declare war on Tibet, they might have allies but their troops cant get to your territory, because there is Permanent Terra incognita between them and Tibet and they sometimes are at war with other countries.
