I think the "right" (or maybe idiomatic is a better word) organisation is an effect of a very important cause - changing the way you think about a software system. Simplistically, OO promises to be a world full of chunks of knowledge and behaviour that politely ask other chunks to behave in a certain way. You have relatively narrow but very deep 'shapes' as levels of abstraction increase. Realistically we all know how that goes :).
In FP the form the structure of the knowledge itself is your primary chunk with a many little chunks of functionality that all know how to transform one shape to another. You have a relatively wide and shallow 'shapes' that all work on a few core chunks of knowledge (i.e. state). To put it another way, I find it really helpful in Clojure to phrase the question 'what shape data do I need and which transformations are necessary'. It isn't quite on its head, but close. You can absolutely still address encapsulation, domain abstractions etc. (http://thinkrelevance.com/blog/2009/08/12/rifle-oriented-programming-with-clojure-2) but start with the shapes of knowledge. All of the above is incredibly simplistic, 'wrong' for some definition of wrong but it is something I wish somebody had told me when I was first starting out :).
