Right now I'm playing guitar fine and I'm coming up with various riffs and I'm quite enjoying them however simplistic they may be. But when I'm trying to get some chords to fit for my riff (well I record the riff and play it aloud while I try to figure out the chords), I'm finding it difficult to find the right set of chords or I think the technical term would be family. So,

I want to know is there anyway or technique that I could use to find the best set of chords for my riff

and thus ultimately make a good song?
