Hi, yes, I've made snack sticks. I make them with a Jerky Cannon from LEM Products.
They don't require a casing.
For seasoning, you can buy any of the pre-packaged jerky seasonings. LEM does sell a mix specifically for snack sticks, but I believe the jerky mixes work just as well.
You can also find many recipes for jerky marinades, etc. at
nullJust Jerky RecipesTo smoke the sticks, since they're pretty soft, I just place them on foil-covered smoking racks. Turn them over about half-way through the dehydration-smoking process.
Go easy on the smoke. Otherwise, your sticks will taste like wood.
Good luck.
