Explanations Given to Bellatrix(paraphrasing taken from The Harry Potter Lexicon):

B: Where were you when the Dark Lord fell?
S: At Hogwarts where Voldemort ordered him to be, spying on Dumbledore.

B: Why did you never make any attempt to find him when he vanished?
S: He thought Voldemort was utterly vanquished.

B: What have you been doing all these years that you’ve lived in Dumbledore’s pocket?
S: Snape claims the Dark Lord is pleased that he did not desert his post.

B: Why did you stop the Dark Lord procuring the Sorcerer’s Stone?
S: Snape did not know that Voldemort had possessed Quirrell, so he thwarted Quirrell because he was “unworthy.”

B: Why did you not return at once when the Dark Lord was reborn?
S: Snape did return, 2 hours later, on Dumbledore’s orders thus ensuring (Snape tells Bella) that Dumbledore continued to trust him.

B: Where were you a few weeks ago when we battled to retrieve the prophecy for the Dark Lord?
S: Snape says his orders were to remain behind.

B: And why, Snape, is Harry Potter still alive, when you have had him at your mercy for five years?
S: Snape tells Bella that murdering Potter would have ended Dumbledore’s trust and Snape’s ability to gather information on the Order of the Phoenix.
