I recently went through this with a Vitus 992.
1 - Find someone with a derailleur hanger to sell, usually because they have a broken frame. Not likely at all if your bike model was made for only 1 year and the hanger is unique to that model.
2 - Find the closest match hanger that is available, and modify it to fit. Drill mounting holes in the correct place, file away some metal, etc.
3 - Get some aluminum plate and make a hanger by hand. Aluminum of 1/8" thickness (or whatever is the closest match) is fairly easy to cut with a jigsaw.
4 - Have a waterjet cutting place make a replacement hanger. You measure up the old hanger, draw it up in a CAD program, and they load the file in their machine and cut the piece.
I did #4. If that hadn't been an option, I'd have done #2. It doesn't have to be pretty. You just need these things to be correctly located: mounting holes, the notch for the axle, the hole for the derailleur, and the tab or hook that the derailleur's B screw sits on. Cut away whatever material inteferes with thr hanger fit in the frame. Derailleur hangers only cost $10 so it's not a big deal to buy one and try modifying it.
