Gas stove + Wok Vs. Induction top + Skillet
A wok is designed to put food in heat at the center and relax some of the heat as you move away from center, and you keeping the food moving in and out of that hot spot so you get an even sear all around. 

To mimic this, use a wide 12 inch or larger skillet (depending on your quantity of food) with high walls, and make it hot. Continuously flip the food over and over and stir is so you get an even seat in the same way. This is called stir fry.

The reason why a wok is desirable is you can manage a lot of food in a wok and move stuff into and out of the hot center quite easily. You can do the same thing in a skillet, but you have to take greater care to not burn your food nor to make a mess throwing the food around.
