Try \mapFoo \lyricmode { ... } instead, making \mapFoo a music
function.  You then iterate through the music using something like

mapFoo =
#(define-music-function (parser location music) (ly:music?)
  (for-each
    (lambda (m)
      (set! (ly:music-property m 'text)
            #{ \markup \foo $(ly:music-property m 'text) #}))
    (extract-typed-music music 'lyric-text)))
