Thin vox
Hey there, what mic are you using and how far are you miking from? If you're using a dynamic microphone, after about 6" you'll lose all your weight. With a condenser, you probably want it about 6" away, further than a foot is usually where you'll start losing some heft.
Be careful with getting too close to the condenser, however. If you're singing right into it, the proximity effect will beef up your vocal, but you're probably going to end up with a really beefy vocal that will not sit correctly in the mix.
As far as EQ goes, I would put +10db and sweep around 235-250 hz, once you find the area that gives that voice some clout, pull it back to +2 or +3db. This is where you can get some unpleasant boominess, so be careful to not add too much.
Another thought is, if you're using a condenser in a small, live room, phase interactions with the close reflections can suck all the meat and potatoes out of your vocal. Try a different room, especially maybe a really absorbant, dead space like a walk in closet full of coats or hang some blankets up.
