Baking bread for fishing bait I would like to experiment a little with new fish bait. So I want to make special bread for fishing with specific aromas and tastes like this bread.

Bread needs to be elastic and rubbery-spongy, so it will stay on the hook, but should not be crumbly. It will be perfect if it can be dehydrated for later use, but after hydration should retain the same characteristics as a fresh one.

According to my small knowledge in baking bread, I think adding more semolina in the bread flour will increase the percentage of gluten. Is there any easy accessible product I can use to make bread with these characteristics?
What about seitan (wheat gluten) (also available in dried form as e.g. chips) 



or fried (and dried, not shown in the picture) tofu bits



or tofu skin?



Pro: All these kinds of food are dryable and rubbery. 
Con: I suspect that you can't make this at home - it would be very time-consuming. (Hm, except the tofu. Buy fresh tofu, slice them into little cubes and fry them. Anthoer con: this might by much more expensive than baking bread :-)
