Just put your methods into a table, then your factory has only one upvalue and you can copy the methods into a new table with a loop.

function clone(t, rv) -- shallow table copy
   rv = rv or {}
   for k,v in pairs(t) do rv[k] = v end
end

local factory
do
   local prototype = {}
   function prototype:method1() end
   function prototype:method2() end
   function prototype:methodN() end
   factory = function() return clone(prototype) end
end
