Assuming that all drops have an equal chance of happening for a given mission, out of all of the single reward void missions (Capture, Exterminate, Mobile Defense, Sabotage) and assuming that you craft any blueprint as needed to get the highest exchange amount, on average the best farming missions would be the Tower 3 Sabotage (26.7/run) and Exteminate(26.3/run), followed by T4 Sabotage(24.0), T4 Exterminate(22.5), T3 Mobile Defense(21.1) and T4 Capture(20.0). The absolute worst is T1 Mobile Defense at a 7.1 Ducats/run average.

For the remaining three void mission types (assuming 20 wave Defense, 4 rounds Interception and 20 minute Survival), the best options are T3 Survival (56.2), T4 Defense (56.1), followed by T4 Survival (45.5), T4 Interception (44.8), T3 Defense (40.1) and T2 Survival (35.4) with the T1 Defense being the worst at 13.3.

I don't have any good numbers for how long it takes (on average) to complete each of the missions, so I can't give an average Ducat/minute rate at the moment, but I know that Captures are usually sped through the fastest, so if you can repeatedly rush a T4 (or ever a T3) Capture that might give you the best return on your time investment, even if they sit in the middle of the Ducat/mission range.

I hope that helps.

Disclaimer: My numbers are based on the current drop tables and exchange amounts and make the above mentioned assumption about equal drop probabilities. Since I'm using averages, small sets of runs are likely to have different results, however, assuming a large enough amount of runs the rewards should average out close to the above (if the underlying assumptions are correct).
