My biggest tip is to demo the entire track just before you go into the studio, as opposed to bringing in some rusty old demo from when you wrote it. That way you know exactly who's playing what where and you can streamline the tracking process enormously.
If you're working without a producer, have a clear schedule for who's tracking what when. Otherwise you end up with the drummer spending ten hours trying to fix a timing problem or the sound of the snare and leave half an hour for all the vocals. <-- BITTER EXPERIENCE
If you have vintage gear, SERVICE IT before you go into the studio. It will still probably break down, so bring everything you need to maintain it. There is nothing worse that having to break down and diagnose a Vox Continental MkII while everyone else is waiting for you to do the organ solo <-- BITTER EXPERIENCE
Change the strings on your guitars a couple of days before recording and play enough to take the PING out of the new strings and stretch them.
Figure out who the squeaky wheel in the band is and have a plan to deal with them.
After you've tracked a vocal, go back and retrack the first few phrases once the voice has warmed up.
