The first time I encountered the Mongols I had played a game as Armenia Cilicia and conquered most of the Middle East besides the fringe of Persia. The Mongols arrived and instantly destroyed the remnant Persian muslim kingdoms which I had yet to conquer then marched on to me. I was unable to stop them and it ruined the game.
Second time I played as Aragon from the start date, spent the game conquering until I had reached Crimea, I controlled from Portugal to Crimea, including Germany, parts of Russia, Africa and most of the Middle East. This time the Mongols invaded from Central Asia instead of Persia and I immediately mobilized 200,000+ troops and crushed them. Heres a tip about fighting the mongols... the more you let them conquer, the bigger their army gets. It is only one stack of 40,000 starting off, and it only becomes impossible to beat by the very tactics the noobs in the previous posts have suggested - i.e. letting them conquer things and letting other nations deal with them.
The "Reconquista" is not possible in DV, as you get badboy points for everything, so you can't let them win at all from the getgo. My suggestion would be to immediately declare war on the Mongols as soon as they appear, even if you are relatively far away, and smash them. OF course, if you are a regional power rather than an Empire, I don't know what to tell you, you are probably doomed. I think the minimum size force needed to kill the mongols would be that of Germany's size realm.
Think of the mongols as Mordor, if you let them mass you will get owned, but if you deal with them when they are small, you won't have to do a suicide mission to mount doom.
