Many of the leaves on my grape ivy are turning papery and dropping. It is happening to leaves of any age and size. The plant continues to provide new growth and appears in no serious danger, but the appearance is not good.

Are there any spots on the leaves beforehand? It sounds like fungal leaf spot. Trim away the infected leaves and make sure the leaves stay dry. Normally, this issue will clear up on its own if you do this, but you should still keep it away from other plants though as it can spread.
