jjp... you're not the first to inquire about bass tabs here, but unfortunately the answer is pretty much always the same. There really aren't any because Phil never plays the same thing twice. The best thing you can do, in my opinion, is learn the signature licks, and then just the song structure. As long as you know the chords and a few scales and arpeggios on the bass you'll have plenty to keep yourself busy. My other advice would be to keep things moving at all times.
