Stakes and mass longbows are your best bet with the english.
English spears suck and suffer from low morale so I would rather use retinues with some armored swordman support, with some heavy billmen to kill the general. Try to lure elephant artillery fire with few mercenary horse archer units as well.

However if you meet timur army 1v1 on open ground, you will still suffer drastic losses. Your best bet is to have your cities/castles upgraded to cannon towers and using the cannon towers to beat them off.
