The book that I have read that comes closest to a comparative study of meditation practices is the Meditative Mind by Daniel Goleman. It compares meditation techniques from a variety of different religions and non-religious traditions. Obviously there is a lot of information about Buddhist techniques (Zen. Tibetean etc..) but it goes into Hindu techniques, Sufism, Christian and secular such as Transcendental Meditation. It covers the dhyanas and the differences between concentration and insight practices.
It was out of print when I bought it but it's easy to pick up a used copy - a quick google picks up loads. It's been a while since I read it but I remember liking it. Flicking through it again now is tempting me to read it again.
EDIT
Sorry - I've noticed that you have asked for practices in general not meditation practices. But I'll leave this answer standing as perhaps part of the answer. It is still a good comparative study

As has been pointed out, this is a vast question, and I doubt it's answerable in anything other than a pile of doctoral theses and then some, but I'll make a small attempt at a piece of it.
I'll point you to one comparative study that could maybe act as a lead in your search. It is "Self-transformation According to Buddhist Stages of the Path Literature" by Jared Lindahl. In it Lindahl compares in some detail the path described by Buddhaghosa in "The Path of Purification" (the Visuddhimagga), with an ostensibly different path described by Dakpo Tashi Namgyal in "Mahāmudrā: The Moonlight".
Obviously this is very far from a complete taxonomy as you were asking, but it at least shows that a comparison/contrast can be done. All you have to do now is repeat what Lindahl has done, for every known practice area, and voila! Let us all know when you're done ;-)
P.S. Dan Ingram talks about connections between the different practice "maps" (as he calls them), in his "Mastering the Core Teachings of the Buddha". Ingram himself says his primary influence is Therevadan practices, especially those taught by Mahasi Sayadaw, but he seems to know enough to be able to make linkages between various attainments outlined on that path and similar attainments on other paths. So that book is (with my usual "don't get too caught up in the Dark Night panic" caveat) is worth a look.
