Some of the units which require a strategic resource should be available in a substitute version, not requiring the resource, but with some kind of drawback.
Iron units' substitutes should be weaker, since they would use copper, bone or whatever they'd get.
Saltpeter units' substitutes should simply cost more, since saltpeter can be extracted from manure with some work.
Oil units' substitutes should require Coal, be slower and cost more. You can make liquid fuel from coal, but you'd rather use oil.
Rubber units' substitutes should require Oil and be a little weaker. You can make synthetic rubber, but the real thing is stronger.
Aluminum units' substitutes should be slower or have shorter operational range.
Uranium units, well - no uranium, no nukes...
I don't know how to make mounted units without horses, but late mounted units should maybe not require horses because one can assume horses to be spread across the world by that time.
