In fact the only weakness that Spain has in this game is the lack of heavy spearmen. And you will need spears against the mongols, so most probable use merks or crusader ones, since you don't have any (exept militia but these won't do). Also you can use tercio pikemen. They will die like flies from the arrows, but you have many. Basically use CK, DCK, spears or pikemen and passive crossbowmen. O, or muskets if you can. They rule. There is a lot of topics on how to fight mongols and timurids here, so search.
