Liamster, here is what I would do if I were you:
1-since you are playing guitar you know what chord progression you are going to use and how many bars each chord lasts, right?
2- if so input those chords in the correct measures in BiaB
3- pick a style that best suits your song
4- mute the instruments you do not want to hear
5- record your guitar while listening to BiaB - turn off your speakers/near field monitors and listen via headphones
6- record your vocal

This is very close to my workflow with the only difference is I input the chords in BiaB, select a style, then export the BiaB files to my DAW and record there.

YMMV

{edit} another thing to try and have fun with is to just input some chords and pick a style in BiaB and play along and write some lyrics.

I phoned my wife and asked her if she wanted me to pickup fish and chips on the way home.
She just grunted.
She still regrets me naming the twins.
