Well I think you really have two options.

The first is going straight Monk and playing like a monk and utilizing your subclass abilities to cover weaknesses such as mooks and such.

The second is doing a substantial dip into tempest cleric for the ability to shove anyone you deal thunder or lightning damage to. The CD doesn't hurt with maximized AOE either. Not something I would recommend just to do but if you have a party that likes to use meat grinder tactics it's solid. You missed some of the higher level amongst stuff but you also get third level spell slots so you aren't hurting.
