James, my understanding is that the tenor guitar is tuned to fifths, usually CGDA or GDAE. AndGDAE is exactly how a mandolin is tuned, though an octave higher than a tenor guitar). So you might seek out mandolin tab for tunes. Even if you tune CGDA, you could still use that tab; you will simply be in a different key. But chord charts and tab for the mandolin are certainly more popular on the internet, so you might look for that stuff instead of limiting yourself to lessons on tenor guitar.
