You can use a thing called auxiliary perspective.

It can be a real pain to set up if you are drawing traditionally, as you can see from this example I drew. Maybe with big paper you could do it all on one page, but you will need to tape paper together if you don't have big enough paper.

1.Draw your normal vanishing point 1 and 2.

2. raw a straight vertical line up or down, so it hits either vp 1 or 2.

3.Add auxiliary vanishing point, in my example I named it vp 3 and 4.

(I also had to just guess where vp 4 was, because it would have been too down to fit even two papers. But you could find it, by just taping more and more paper together.)

4. use it to draw the incline planes you have.
