as far as the mpen vs AP on any champion, I usually add up all of a champion's damaging skills with AP ratios and divide that by the sum of all the ap ratios in those skills. Results higher than 400-450 tend to favor  magic pen while values below that favor flat AP. In Vel'koz's case,  thats 1605 base divided by 2.325 AP ratio, equating ~690. Meaning you need that much AP to double his damage. Compare this to, say veigar, with a 1080 base and 2.8 AP ratio equaling ~385, who scales well off of alot of AP.

So for Vel'Koz yes CDR and mpen are your goto stats. and I would reccomend DFG over Dcap. DFG will help his huge base damages better than a Dcap, plus it'll grant you cdr and a nice chunk of AP. The active is there incase anyone gets close (which with Vel's low mobility is likely) and you can turn on them. Last item is defensive, likely a zhonyas or banshees depending. Rylais is another option if you want a reliable way in procing innate (15% is plenty combined with the rest of his CC). To recap

Sorc shoes, Athenes/morellonomicon, Liandry's, Void Staff, DFG, zhonyas/banshees/rylais (last cdr from blue buff or brill pot)
