Wix is a toolset that expects you to do a lot of the heavy lifting yourself. There are no Visual Studio automatisms.
To build a Wix file, you will need to type it manually or use the tools that came with the toolset. In this case, the tool you want to use is heat.exe, the harvester. It can scan various places (folder, projects etc) and produce a wix file that will install all files it found.
See this link for a very good documentation including examples
