Here are the conjugations for future tense words:

e emos
as eis
a an

These endings are the same for er, ar, and ir verbs.

There is no stem before the suffix; you just use the infinitive.
ex: you will eat = correras

However, there are irregular "stems." Here they are:
poder = podr
poner = pondr
sailr = soldr
tener = tendr
venir = vendr
decir = dir
hacer = har
querer = querr
haber = habr
saber = sabr
