There's no need to do this in LaTeX-mode-hook, it should be enough 
to have 

(add-to-list 'TeX-view-program-selection '((output-pdf 
"Zathura")))

in your init file. Doing it in LaTeX-mode-hook means it's executed 
each time you open a LaTeX file, which is harmless but 
unnecessary.

Note, though, that Zathura is defined in 
TeX-view-program-list-builtin as "Zathura" (note the capital Z), 
so that's what you need to put in TeX-view-program-selection. (I 
suspect that is the cause of your troubles.)

As for the entry for Evince in TeX-view-program-selection, I have no idea if 
that conflicts, but if you need to get rid of that, you could do:

(setcdr (assq 'output-pdf TeX-view-program-selection) "Zathura")

instead of the add-to-list invocation above. But I suspect that 
AUCTeX will simply use the first matching entry in 
TeX-view-program-selection, so the entry for Evince shouldn't 
cause problems.
