I have done some serious coding into functions.php thereby changing the reputation system into a Thanks meter as follows. How do I go about changing this into a plugin and share here?

Well firstly you'd need to find all the hooks that are intended to change what you changed manually. That's really the whole premise of what you're doing, changing the postbit via a postbit hook so that your thanks meter shows instead of a rep #, changing the text with a language file, etc..
