I don't have a lot of experience with jerky - I've made a couple batches with the hi-mountain teriyaki cure. For the first batch, I followed the directions that came with the cure and did not think the finished product had a very strong teriyaki flavor.
For the 2nd attempt I marinated the meat for a couple days in a liquid teriyaki marinade, then applied the hi-mountain cure following the directions on the package. The finished product was great - good teriyaki flavor.
