Well saying "it is as you say" is pretty much saying it, isn't it?
The accusation that he claimed to be the "Son Of God" was made against him, which would mean the death penalty, and he never denied it or defended himself.
Anyway...
Matthew 16:15-17
"But what about you?" he asked. "Who do you say I am?" Simon Peter answered, "You are the Christ, the Son of the living God." Jesus replied, "Blessed are you, Simon son of Jonah, for this was not revealed to you by man, but by my Father in heaven.
Peter calls Jesus the Son Of God and the Messiah and Jesus supports that statement
John 8:58
I tell you the truth," Jesus answered, "before Abraham was born, I am!"
What's missing in the English translation is that Jesus used the same phrase as is found in Exodus 3:15 when God tells Moses that he, God, is the "I AM. This is a phrase that linguistically cannot be used without actually claiming to be God. When God used that phrase in Exodus, he was making a statement about himself, when Jesus used it later on, he was saying the same thing
Matthew 9:2-6
Some men brought to him a paralytic, lying on a mat. When Jesus saw their faith, he said to the paralytic, "Take heart, son; your sins are forgiven." At this, some of the teachers of the law said to themselves, "This fellow is blaspheming!" Knowing their thoughts, Jesus said, "Why do you entertain evil thoughts in your hearts? Which is easier: to say, `Your sins are forgiven,' or to say, `Get up and walk'? But so that you may know that the Son of Man has authority on earth to forgive sins...." Then he said to the paralytic, "Get up, take your mat and go home."
No one can forgive another except for what has been done to them. I can't forgive your wrongs against a friend of yours. I can only forgive your wrongs to me. Ultimately, all sin is against God, and therefore only God can forgive sins. Here Jesus is claiming to forgive the paralytics sins, not his sins against Jesus, but his sins in general. The teachers of the law recognized what this meant, that he was claiming to be able to forgive sins, something only God, the ultimate wronged party in all sins, could do. For Jesus to claim to have the power to forgive sins is Jesus claiming power reserved to God, thus making Jesus equal to God. So the charge of blasphemy was correct if Jesus was not indeed God..
This passage is mirrored in Mark. Jesus offering to forgive sins, and the stunned reaction of those around him who understood the implication, was repeated several times, include Like 7:48,49
There are more examples. Usually Jesus didn't go around and say "I am the Son Of God" but merely said thins and claimed things only God could say and claim. I can dig up some more if you'd like
Incidentally, Jesus oftened called himself the "Son Of Man", which is an intersting term on the surface. What Jesus was using was the same term found in Daniel 7:13,14
"In my vision at night I looked, and there before me was one like a son of man, coming with the clouds of heaven. He approached the Ancient of Days and was led into his presence. He was given authority, glory and sovereign power; all peoples, nations and men of every language worshiped him. His dominion is an everlasting dominion that will not pass away, and his kingdom is one that will never be destroyed.
Not exactly a claim to be God but a very significant title for oneself, probably a claim to be the Messiah.
