Here are some templates for writing SOAP notes. There's a PDF and a DOCX (Word document) version. But instead of downloading one of these, consider using Quill for your notes instead! The first five notes are free, so why not?

The PDF version of the SOAP note template can be printed out and then written on, which might be useful during a session. Meanwhile, the DOCX version of the SOAP note template can be opened up in Microsoft Word, letting you edit directly in that document.
