For both wolf and bear builds, 2H weapons are your best DPS option. You take the Natural Fighting feats to boost doublestrike, Melee Power, and (for bears) Strikethrough.
The THF feats don't apply directly to animal forms, but they can be used to unlock Strikethrough enhancements that stack with Natural Fighting (
test results here). That is the "secret sauce" to heavily-MCed bear builds like
this one.
If you want to max out the attack speed of wolves (which is really their forte vs bears) you need Winter Wolf form + Swift Hunter (tier-5 Nature's Warrior) which is also what grants Evasion. This constrains your multiclassing options, since most classes put their crit bonuses in the tier-5 Enhancements (e.g. barbarian).
Given that you're already going for cleric 5 for the Strength domain feat, you might as well do cleric 6 for the deity ability like Unyielding Sovereignty. You could do cleric 7 for level 4 spells, but I don't know that you need any of them unless you really want Divine Power.
So something like druid 12 / cleric 6 / barb 2 should have a decent mix of DPS and survivability. For enhancements: tier-5 Nature's Warrior / tier-4 Nature's Protector / tier-2 Frenzied Berserker. Plus you'll have both winter wolf and dire bear forms, so you can experiment to see which you prefer.
