It seems that the cause of the situation of curdling soya milk in coffee is that the acid from the coffee curldes the proteins and/or fats in the (soya or other) milk, being catalysed by the heat of the coffee; so that's what needs to be mitigated.

Tofu, also known as bean curd, is made by coagulating soya milk and then pressing the resultant curds into soft white blocks. This process can be achieved by adding the soya milk to an acid or to salts like calcium sulfate. These various forms of tofu are washed to create a food product with a variety of textures and uses.

But the general consensus in the scientific community seems to be that soya milk curdles in coffee because the coffee is acidic. With that in mind I did try making ground coffee in a cafetiere, in the hope that it might be less acidic, but that didn’t work when I was using the Tesco milk.
