Single quotes denote string literals. If you're referring to arguments passed to the function, you should not surround them with quotes:

UPDATE PUBLIC.vendormaster vm
SET    vendortypeid = @vendortypeid,
       email = @email,
       misbapsid = @misbapsid,
       businessname = @businessname,
       taxid = @taxid,
       primarycontactname = @primarycontactname,
       primarycontactemail = @primarycontactemail,
       additionalname = @additionalname,
       primaryaddress1 = @primaryaddress1,
       primaryaddress2 = @primaryaddress2,
       primarycountryid = @primarycountryid,
       primarystateid = @primarystateid,
       primaryzipcode = @primaryzipcode,
       ischild = @ischild,
       parentid = @parentid,
       isactive = @isactive,
       mobileno = @mobileno,
       createdby = @createdby,
       createdon = @createdon,
       isdeleted = @isdeleted,
       deletedby = @deletedby,
       deletedon = @deletedon,
       updatedby = @updatedby,
       updatedon = @updatedon,
       primarycityid = @primarycityid,
       status = @status
WHERE  vm.vendorid = vendorids
