Hi DMan,
You can use themes in your street hockey games like in on-ice games, but why leave it just to that. Basketball is good game for coordination and skill. You can use themes or different rules, eg. try play basketball with offsides. Many teams here use handball to train their break out plays, when the pace right it's good aerobic workout too.
I guess one practice could be like this:
Dynamic warm up and/or handball + speed and/or plyometrics + games + cool down, dynamic stretching
