A C is a C.  How it looks on the staff depends on the clef.  LilyPond will
put it in the right place for you.  If you have indicated the correct pitch
and octave all you need to do is tell LilyPond which clef to use.

The "f" line is the 4th line in bass clef.  In tenor clef the 4th line is
middle C.  But, changing clefs has *nothing* to do with transposition.
Transposition would result in a different pitch being printed.

Mats is correct when he says trombones read sounding pitch.  This is true
when trombones are reading bass, tenor and alto clefs.
