Well, if you go to this thread: Praxeology: reading list you will find plenty of information concerning methodology.
In particular I’d recommend Rothbard’s Praxeology: The Methodoloy of the Austrian School, Hoppe’s Economics Science and the Austrain Method (this is the best IMO), Saleron’s What is a Causal - Realist Approach and Huerta de Soto’s The ongoing methodenstreit of the Austrian School.
Those are the ones that I found very useful anyway.
But as I said, if you go to that thread there’s plenty.
