Yems criticised referee Kevin Johnson for his display and said the performance from his players was not acceptable.
Johnson sent of Orient's Hector Kyprianou in the stalemate but Yems was not happy with his performance overall and said his decisions 'could have caused ructions'.
Yems, in his post-match interview on the club's website, did not think his side deserved to win the game. He said: "I don't think their keeper had to make a save. Not happy at all.
"We just weren't at it, I don't know what the reason is.
"The lads have got to look at themselves sometimes because that ain't acceptable."
The goalless draw follows the 3-1 defeat to Cambridge United on Saturday.
