Mix together marinade ingredients and marinade steak for at least 20 minutes (or up to 3 hours) in sealable plastic bag.
Meanwhile, prepare vegetables using a hand slicer, sharp knife or mandolin.
Heat 2 tsp olive oil in a medium-sized frying pan and fry enoki mushrooms and bean sprouts with 1-2 tsp of soy sauce for 3-4 minutes until vegetables are softened and cooked. Take off heat and set aside.
Remove steak from marinade. Heat 1 tbsp olive oil in large frying pan until oil is smoking. Add steak and cook for 2-3 minutes per side until cooked medium-rare.
Submerge rice paper wrap in hot water for 7-8 seconds, smoothing outwards with your fingers. Lay on a clean, flat surface while still semi-firm. They will soften out. Alternatively, you can place wraps in between two damp towels for 5 min and then rinse with cold water when ready for use. This is an easier but more time consuming method. If wraps get sticky you can always rinse with cold water to smooth them out.
Assemble wraps by putting a small amount of each ingredient in the centre of each rice paper wrap and then fold top over by stretching the rice paper wraps. Tuck in each side while squeezing the wrap together, much like with a tortilla wrap. Finally, stretch the final half overtop and make it stick with a tiny bit of water if necessary.
Cut with a hot, sharp knife and continue until all wraps are made.
