The MSc i want to apply for requires a research proposal to be submitted with the application. How can i find out how to do one properly?

Your proposal should include:

1 why the research is needed and what is the general area of current concern.
2 what is already known about the proposed research.
3 what information resources and methods will be used to answer the research questions.
4 what are the intended/expected outcomes (contributions to theory, reports, materials, etc).

Please do mention in which area you are going to write the proposal?
