To make the okonomiyaki pancakes, combine the cabbage, stock, flour, tempura bits, onions, yam, ginger, baking powder, egg and some kimchi in a bowl. Whisk together but do not totally blend. Pour the mixture onto a hot griddle (at least 400 degrees F).
While mixtures thickens and cooks, begin to add the sausage and peppers to the top of the okonomiyaki.
Once cooked on the bottom, flip the okonomiyaki and sprinkle with the cheese. Allow the okonomiyaki to cook until equally done on both sides, 1 to 3 more minutes.
Drizzle okonomiyaki sauce on top, then drizzle with some mayonnaise. Garnish with aonori and more tempura bits.
