Please always (try to) give a minimal working example. This could 
something like the following for choral music:

%%%%%%%%%%%%%%%%%

\version "2.19.80"

\new ChoirStaff <<
  \new Staff { \key f \major d' } \addlyrics { "blah" }
  \new Staff { \key f \major c' } \addlyrics { "blah" }
>>

%%%%%%%%%%%%%%%%%

You can transpose the whole score by simply adding the \transpose 
command before the music. This will transpose pitches and key signatures:

%%%%%%%%%%%%%%%%%

\version "2.19.80"

\transpose f as \new ChoirStaff <<
  \new Staff { \key f \major d' } \addlyrics { "blah" }
  \new Staff { \key f \major c' } \addlyrics { "blah" }
>>
