Before going 'legal' (especially as you seem to have nothing specific in writing), why not talk to your manager, or the most appropriate person about it. Explain, why you're worried ("We agreed there would be options grants, and I know you're a man of your word, but it has been a little while now, and I wonder if you could explain why there has been a delay, and when we can expect to get them"). Odds are that it is nothing malicious, or dodgy, but if you're at a fast growing startup there are probably lots of other things on your CEO's plate, and these might have been put near the bottom of the queue. But it is worth talking it through (there are lots of reasons why it might be taking a while- lawyer on holiday, investors need to sign off etc). If your boss is evasive or refuses to discuss specifics, then you can start to worry! (I'm in the UK, and my options took a year and a half to get finally sorted and signed off, but I trusted my boss, so didn't feel I needed to worry about it!)
