A pretty quick & easy, good seitan recipe that I've modified slightly from one that I found from a very good (Finnish) vegan blog, ChocoChili.
2,5 dl gluten flour
1,25 dl gram flour
1-2 tea spoons of different spices of your liking (I usually use curry, smoked paprika, garlic powder and dried coriander)
1-2 tea spoons of vegetable stock powder (or ~half of a vegetable stock cube mixed first to the water)
1,5 dl water
1) Mix all the dry incredients first
2) pour the water slowly while mixing with a fork or something. After pouring all the water, ditch the fork and just knead it by hands.
3) Keep kneading the seitan dough until all of it's mixed. Some of flour might not mix into it, so if you want you might want to pour a TINY bit more water if you want to get all the flour to mix into the dough (and I do mean TINY). The dough shouldn't be too sticky at this point (if it is, then there might've been too much water).
4) Form the dough into a long, round-ish form until it looks a little bit like a big, long yellowish-light-brown turd. Cut it into steak like slices that are about 1-1,5cm thick, then cook them for 30 minutes in:
1,5 liters water with
2 vegetable stock cubes
0,25 dl soy sauce
0,25 dl balsamic vinegar
NOTE: keep in mind that the seitan pieces will expand a lot (like, 3-4x the size they are before cooking, at least), so you might need a fairly large pot/kettle for a batch of seitan of this size. If you don't have any large kettles, I'd suggest maybe halfing the recipe.
Also, the soy sauce and the vinegar aren't completely necessary, I've made this without them and it's perfectly fine.
And that's about it, after they've been cooked for 30 minutes, take them out of the water, they are ready for use (pro-tip: you can reuse the remaining water to cook rice or something, don't waste it). After that you can marinade them overnight in the fridge or just fry them in some oil & spices and serve it with some sauce & rice/couscous/potatoes/whatever. The way I do the recipe (throwing the spices into the dough), it doesn't really need marinading, but of course you can if you want to.
And a very easy sauce you can make that I kind of invented
You'll need
a batch of the frying-ready, cut to smaller pieces seitan I've described above
2-4 dl of coconut cream (depending on how many people you have to feed)
2-4+ teaspoons of cinnamon powder (depending on how strongly you want the cinnamon to taste)
2-3 teaspoons of curry powder
60+ grams red curry paste (depends on how spicy you want the food to be, though be warned, if you put too much of it can kind of overpower all the other flavours)
After you've cooked the seitan in the water for its time, take the seitan pieces out of the water, cut the seitan "steaks" into smaller, bite-sized pieces, fry them for a little while in some oil & spices of your liking. After the seitans are done, pour 2-4dl of coconut cream onto the frying pan they are in, mix in the spices & the red curry paste and voila, you've got yourself a pretty simple yet tasty seitan with a nice sauce à la Famassu.
I just kind of threw in the cinnamon because I got a lot of it from my parents and don't really do much baking where I'd use it. I needed to find some ways to use it in other cooking and have just thrown some of it into my cooking at times. It works pretty well with the coconut cream & red curry paste and gives it a bit of an Asian/Indian vibe.
