How can I make a vegan turkey-skin substitute?

I recently tried to practice making a Seitan based vegan turkey tube using this recipe. To test results for different cooking methods, I split the final dough in half before baking, made one that was just turkey-dough and one that was a turkey-dough and stuffing roulade.

Both turkey loaves came out well. However, the recipe gives instructions on fabricating a kind of "turkey skin." Basically, once the turkey is done baking, remove from oven, place on a pan, wrap with yuba (bean-curd skin from making soy milk, similar to spring roll pastry), brush with sesame oil, and bake until browned (about 45-60 minutes, brushing on more oil occasionally). The results were basically a distracting pastry shell wrapped around a seitan loaf; it did not appear to adhere to the surface of the loaf at any point. It was difficult to cut and had a difficult texture compared to the ease of the seitan.

To give an idea of the results, here is a picture of some scraps from the plate:

The instructions did not give a specific detail as to what to expect, or really how to qualify the results of the "turkey skin." As such, I am at a loss as to how to improve the results.

So:

• Have you made or had a yuba wrapped item, where the method above was somehow applied but with a more successful result (as in, the yuba adhered to the surface of the loaf, the yuba cut easily, or had a more delicate texture that didn't contrast as much)?
• Of the three fails (adherence, cutting, texture), what methods would work to improve them? (E.G. Would brushing oil on the loaf before help or hinder yuba sticking to the loaf, would it help soften the yuba?)
• Is there any method of softening the yuba and making it more delicate before applying it? Would this be beneficial to the desired result? Why?
• Could tweaking the temp:time of baking with the yuba wrap help? (i.e. Lower-slower breaks down fats, connective tissues in animals... is there a similar compound I am shooting for in yuba?)
• Can yuba be prepared to mimic the soft-toughness of turkey skin? How?
