I have just found another version of this recipe. It's not TM one, but shouldn't be too hard to translate. This is the link:

(makes 1 4 serving pancake)
Ingredients:
1 cup flour (I used whole wheat flour)
3/4 cup dashi (or water)
1 egg
1/4 of a cabbage, about 2-3 cups packed (shredded)
1 carrot, about 1/2 cup (grated)
1 small zucchini, about 1 cup (grated)
1 green onion (chopped)
3 slices bacon
okonomiyaki sauce (or Worcestershire sauce)
mayonnaise
green onion (chopped)
Directions:
1. Mix the flour, dashi, egg, cabbage, carrot and zucchini in a large bowl.
2. Heat some oil in pan.
3. Pour in mixture and top with the bacon slices.
4. Cook on medium heat until golden brown on both sides, about 5-15 minutes per side.
5. Top with okonomiyaki sauce, mayonnaise and green onion and slice.
I realise bacon isn't vego, just leave it out. Apparently the bacon cooks when the pancake gets flipped.
