In situations where venues are small enough that only vocals and effects go through the PA system, you might hear some very "wet" vocals because there is nothing else in the mix to obscure them.
Small stages with loud guitars and drums only need the less loud sources amplified, like vocals, effects (non existent in nature!), keyboards, electronic drums, and acoustic guitars.
Board tapes from small venues thus are commonly heavy on the effects.
It is typical for stage monitor feeds to be 100% dry, and have zero added reverb or delay. It's tough enough to point speakers at microphones and not let them feed back without sounds hanging around longer than necessary (additional reverberation would be bad for this)
If vocals sounded reverb-y at the show, then the recording will show that.
I would just mix it a little lower than otherwise, but be careful not to bury the vocals too much.
Some types of music lend themselves to lower vocals, like grunge and metal... wanna hear it? CRANK IT UP.
Pop mixes generally are more intelligible, so a pop style band you can't really get away with burying them, so it's just gonna sound like it sounded.
Dunno if this helps at all.
