To create a whipped sweet you just need some fat. Vegetable margarine or non-light coconut oil will suffice. Of course the ingredients ratio is different from a regular recipe so you will have to make some attempts. You have to use a wooden spoon and you should mix from bottom to above to avoid destroying too many air bubbles.
Actually I've seen recipes that just use 3 ingredients to achieve a fluffy texture.
Of course you will not achieve the same exact texture of a non-vegan pancake, but in general I prefer almost all vegan variants over sweets.
The cream should be whipped with a whisk, then you mix other ingredients later using a wood spoon (from bottom to above), the reason is that if you first add other ingredients the cream do not whip properly, while if you mix it too strongly with a metal spoon you destroy the air bubble and hence the whip. Also ingredients ratio are different: depends on fat concentration of the coconut oil you use, check the % in weight which is fat and use that to compute a new dose.
Usually butter have 80% fat. A simple computation, assume your coconut oil have 70% and in your recipe you were using 200gr of butter,
then you need:
(1,8/1,7) * 200 = 211 gr of oil
Of course keep in mind that the lesser the fat in the oil, the more you may need, and eventually some fatty ingredients may have a too low concentration of fat for whipping to happens ( the % of ingredient that is not fatty actually prevents whipping).
