I think the general process is the same. You define your components, try to decouple them as much as possible and implement them. One thing that is different from other languages: try to write as much pure code as possible. This is great for creating composable components.
There are several different ways to structure your programs. The Utrecht Haskell Compiler is structured using attribute grammars, which is (similar to) aspect-oriented programming.
Another architectural pattern you see a lot is that a program is provided as a library and a very small main function. A very good example of this is XMonad.
You could also look at http://www.haskell.org/haskellwiki/Haskell_in_industry, which gives some pointers to commercial projects and how they are structured.
