Is there any instruction to move directly the last 4 bytes from a YMM register to EAX? As far as I know VMASKMOVPS can be used to move from YMM to memory and from there I might be able to move the data to EAX but I am looking for a better approach, if there is one.

Is VPEXTRD what you're looking for?
