Don't use the latex export function as it will give you a full latex document not just the latex encoding of  your formulas. Instead highlight the text and select "Edit-> Copy To->Latex" from the menu.  This just paste the code into WordPress. 

A issue that may crop up that the copy method above includes the latex delimiters, $ ... $ for inline equations and \[ ...]\ , or sometimes even no delimiters. It all depends I think on whether you have copied an entire equation or just part on one. Anyway, you have to know what the WordPress plugin expects regarding delimiters and then make sure what you pasted matches.
