Assuming the song doesn't change tempos (it can change style, from slow to fast without changing BPM), you can record a track equal to the length of the song with just a metronome. Now, figure out the number of measures that the drums play, and have your drummer play along with the metronome. He won't get off tempo when he's not playing because the metronome will be steady clicking to keep time.

Once you have the drums laid out the bass usually comes next, then rhythm guitar, or vice versa depending on which musician is tighter. Finally add the lead guitar on top of that. That's how me and my brother would record when I went up to his house last summer, and it worked quite well.

One thing you might note - It might be best to keep a simple, easy beat on the drums when recording them at first and then once all the other tracks have been laid down, the drummer can come back and play something more complicated over the whole thing, recording on a seperate track. This allows for him to take some chances and do some fills in relation to what the guitar and bass are playing without worrying about screwing up the song. If he messes up he can start over, no problem. Once you get the final product of the drums, you can delete the original, simple drum part.

Hope this helps, and good luck ;)
