Do what fits and try and grasp what direction you're band is going with the song. Play along with them, don't just be an echo, but don't force them to go in a direction that is undesired that throws off the entire composition. Sometimes you have to conform to the rest of the band and lay down something you feel is dull, but that doesn't limit you as long as you don't get carried away. Alot of it relys on your band mates as well, so share what you talked about here with them and see what unfolds.
Also, Try to throw in alot of technique mentioned previously to accent and highlight parts of the song.
