What documents do I need (I'm British) to apply for a Chinese tourist visa in the Czech Republic?

I am British and I'm working in the Czech Republic. What documents do I need to supply the chinese embassy in Prague for a visa application? I am applying for a tourist visa and I have ready on the website that I need a piece of paper indicating that I can stay here....I am an EU citizen and do not have a visa or other piece of paper saying that I can be in the Czech Republic.
