When you say Northern OBX, are you referring to the Corolla area? I've fished Back Bay a few times, which is connected and very similar so I'll try to help a bit.
I've found the canals and creeks easier to break down than the wide open sound or miles of shoreline. Some hold fish, some don't and I've found that to vary day to day. I typically cover water with something like a bladed jig, buzzbait or spinner bait until I find an area with fish. Then I'll slow down and pick it apart flipping a T Rig or Wacky. I'll also fish hollow body frogs, toads, flukes, swim baits, cranks, etc. There's plenty of things they'll eat.
I suspect there's plenty of duck blinds down that way too. They're a good thing to check since it's one obvious piece of cover you can break down quickly. Hit a couple and you'll know if that's a pattern worth running.
If I'm not finding them in creeks, canals, or on duck blinds then its time to cover water. If the water's up in the bank grass then I'm throwing buzzbaits, speed worms, swim jigs, etc. If I'm fishing off the bank, I'm going with chatterbaits and rattle traps.
I'm sure there are guys who have spent enough time out there to have found hidden honey holes in the middle of nowhere, but I aint one of them.
The last thing I'll add is to be cautious in your kayak out there. Sometimes when you're fishing in those creeks or canals, you don't realize how much the wind has picked up on the main sound. I once made a long run across Back Bay to fish some canals and didn't notice the wind picking up. By the time I left and headed back I was dealing with 30mph and 2-3 footers in my face. Nothing for a boat, but my overloaded kayak was taking on water and I barely made it back without sinking. If you find yourself in that situation, hug the shoreline. At least then if you have to get out to bail water or you flip, you should be in thigh deep water while you're getting things right again.
