Use cycleway:right:oneway (resp. cycleway:left:oneway) to specify the oneway properties of the cycleway on the right (resp. left) hand side of the way.
To indicate that the cycling traffic flows in the same direction the osm way is oriented (as given by the geometry of the untagged osm object), use the value yes (or 1). To indicate contra-flow, use -1. For bidirectional flow on that side, use the value no.

Adding these defaults is unnecessary tagging.
If the way does have oneway=yes, yes is used as an implicit default for both sides (regardless of handedness). In other words, a cycleway on the left side of a one-way road in a country with right-hand traffic is not assumed to be a contra-flow lane (unless explicitly tagged with cycleway:left:oneway=-1).
Because of the defaults, the most likely explicit use is for bidirectional or contra-flow lanes/tracks, but if you know of an exception, please add it to the examples.
