Indiana is District 15 - you can use this link:
http://cycleusa.com/dist15/
and find where the racer are, phone numbers of the tracks and district officers, etc.
Basically - you just go to a race and sign up for your AMA card and district card and start racing.
You could also go to a race to just watch and see how things all work out and sign up for your cards before you try an actual race. What size bike do you ride?
