As described at the top of
http://lilypond.org/doc/v2.6/Documentation/user/out-www/lilypond/Font-selection.html#Font-selection
the default font for most text output in LilyPond is New Century
Schoolbook. The same section also includes examples of how to modify
the font. However, you may have to combine that information with
that of 
http://lilypond.org/doc/v2.6/Documentation/user/out-www/lilypond/Entering-lyrics.html#Entering-lyrics
http://lilypond.org/doc/v2.6/Documentation/user/out-www/lilypond/Layout-tunings-within-contexts.html#Layout-tunings-within-contexts
and
http://lilypond.org/doc/v2.6/Documentation/user/out-www/lilypond/Changing-context-default-settings.html#Changing-context-default-settings
(and maybe more from Chapter 9.)

I deliberately don't give you a more specific answer, since the same
principles apply to all settings you can do in LilyPond so you have to
learn the general ideas sooner or later anyway.
