Well, everyone has their own strategy/plan when songwriting. And you'll eventually develop your own pattern after you practice songwriting long enough.

I would suggest start with the Chorus, with a simple progression. When figuring out the Chorus, try and get an idea of the song in your head. Then work backwards, make a verse which can easily be just a quieter/lighter verse of the chorus or something.
