They are pretty much the same as any other recording endeavor and recording the same way. Vocals and solos are typically done last, so ou just don't do the vocals.
I typically record the drums first- in my case its programming drum machine software. Depending on the song I'll do rythm guitars or bass next. Then bass or rythm, whichever I didn't do first. Last, add and harmony secondary guitar parts and its a rough song.
Solos and vocals fight for what comes next, but I usually record lead then backing vocals. Sounds like you don't have to worry about that. So you'd add solos and instrumental pieces and, voila! you're done.
Take care,
Chris
