This isn't the right forum to post this in, but I'll give you advice anyways.
What is the theme of the fic? Sad, adventure, action, dark, mellow, etc...? Go with whatever tone you feel from it. The idea to making a song is that you feel the emotions inside you and channel them to form a song. In terms of writing lyrics it's the same idea.
