Your question actually falls into two different areas. First, for general information on DMPs, we would recommend looking at DMPtool (https://dmptool.org/). Always check for funding guidelines. Additionally, check with your institution to see if templates are available. For the second part of your question, we recommend http://re3data.org as a good source of information on domain repositories. These are a great starting point, but are by no means comprehensive across the entire research spectrum. We recommend coordinating with subject specialists and/or a data librarian to further explore in any given area. If your school has an institutional repository, check to see if they accept research data, and check with funding mandates to see if there are required guidelines for data sharing repositories. Researchers in a given field may have strong discipline specific repositories, while other fields may have none.
