I haven't tried it in Jerky yet but I used Waltons "Willies" snack stick seasoning in some sticks and am a fan. They have a version for jerky too that I intend to try.
Walton's Bold Jerky Seasoning is a custom blend formulated off our most popular snack stick seasoning! This seasoning has an awesome flavor with just the right amount of heat, creating a savory sweet taste that is perfect for jerky!

I've been happy with most of the waltons products so far if a different one sounds better.
I usually do the soy sauce, brown sugar, Worcestershire mix from our pantry but this year I picked up some pit boss hickory and peppered kits on clearance at lowes. They both are good but the hickory has been a favorite from everyone that has tried it.
Show off the versatility of your grill or smoker with a Jerky Kit from Pit Boss Grills. Put away the dehydrator and go low and slow on your Pit Boss Grill to achieve bold, smoky flavor. Each kit comes complete with three seasoning and cure packets, enough to make three batches of jerky. Just add...
Base
2 lbs venison + 20 % fat
3t Garlic powder
2t Onion powder
3t Salt
3t Pepper
Teriyaki
Base + 2/3 cup teriyaki glaze
Sweet and Spicy
Base + 1 cup brown sugar
2t ground red pepper.
Mix this together and put into the jerky cannon. Put directly on the smoker grills and smoke at 180 for about 2-3 hours to your desired texture.
This is our favorite one so far. You make the base, then can also do teriyaki or sweet and spicy. We like all 3 flavors. I put it in the Jerky Cannon and squeeze it right on the smoker.
