The Isle of Siptah's wildlife is spread a little thin in certain areas, so it can be tough to find a consistent source of hide. Most of the beasts around the center of the map offer Thick Hide, which is a good option. If you gather a large amount of Thick Hide, you can strip down a portion of it into the regular hide, which you can then tan into regular leather. This method should give you a sustainable supply of both regular and thick leather to use in crafting Hardened Leather later on.
