Vegetarian / meat substitutes availability

Hi,

I am staying with a family here in Shanghai and primarily eat with them. I am a vegetarian (no meat, no fish but dairy/eggs are ok) but they are not and so I am looking for options for meat substitutes to have for dinner. In the UK I would use things like Quorn and soya products. What kind of things are available here other than tofu (something I don't mind but don't know how to cook, any recipes welcome)?

Obviously I eat vegetables/salad etc. and can prepare dishes just using them but sometimes it is good to have a 'meaty' type thing so that they can have that instead of the meat that they are having and share the side dishes.

TIA.

J.
