When it comes to working with MIDI in lilypond, your best bet is always
to put your music in variables and use a separate \score dedicated for
MIDI, where you can put in only stuff intended for MIDI and leave out
everything else (or conversely, put in stuff needed to make MIDI work
nicely but shouldn't appear in the typeset score).

So I would put the music in one (set of) variable(s), and the lyrics in
another variable, and then in the \score block intended for typesetting,
use both (set of) variables, while in the \score block intended for
MIDI, leave out the lyrics variable(s). Something like this:

        music = ... % put your instrumental notes here
        lyrics = ... % put your lyrics here

        % This block is intended for layout
        \score {
                \music
                \addlyrics \lyrics
                \layout {}
        }

        % This block is intended only for MIDI
        \score {
                \music
                % N.B. don't put \lyrics here
                \midi {}
        }

Perhaps this page might help?
