Just wanted to share my experience; for metal and hardcore bands (who always send me references like Trivium, As I Lay Dying, Avenged Sevenfold, etc) I've always achieved the "click" they want from the kick drum by tuning the beater side head really low, like almost flabby. I tried it with toms, and managed to get similar results, but they can't be too loose or it just sounds crappy.
But of course, this all means nothing if the drummer taps on them like a girl. I make sure they hit their toms real hard because that's where the click comes from. With good tom tracks, I use EQ as a last resort, even then just like 2 or 3 dB at most at the "sticky" areas (which I can't really specify, but usually around 5 KHz).
If all else fails, I just insert Drumagog, look for some really clicky tom samples and EQ rape them further if necessary. >=P
EDIT: I remember reading about how sometimes engineers would stick some sort of metal pad or something at kick drum beater's point of impact to get even more click out of their kick drums. Not sure if this will work for toms, though?
