If you actually hear someone speak with an accent, a lot of times they say words just like people lacking ones do, save for some shortcuts in words they take like "y'know" and stuff like that.
What I would do, to save your sanity, is just establish that this person has an accent. Truly, anyone that would be reading the story will think to themselves "Oh, this book tells me this man has an accent. I can imagine how he sounds like as I am reading the words he says".
The only exception might be people whose mother tongue is not English, and some (but not everybody) don't speak with all the necessary words in a sentence. Even fewer speak in third person. I don't see this often in books except for a couple fantasy novels where the other side spoke very little "human" tongue.
