How do you form the past tense of To bid?
I had discussions about this in my university days.
Would you say, 'I bid ten pounds on that vase yesterday.' or 'I bade ten pounds on that vase yesterday.' ?
I think technically, it's bade but my tutor said that bid was acceptable. Personally I don't know anyone who would say bade.
Also, do you pronounce bade like blade or like bad?

Bid has two different meanings, for the most part. And bade is the past tense of only one of those meanings.
You bid at an auction, and it's the same whether it's past or present tense.
But bid used as a command or order can use bade as a past tense.
"I must bid you farewell," can be "We bade each other farewell."

Honestly, I probably would have reworked the sentence to say, "I put in a bid of ten pounds on that vase yesterday." And I never would have used it in the context of an order or farewell.
Google says that the verb bid—meaning (1) to offer, (2) to command, or (3) to invite—used to be inflected bade in the past tense and bidden as a past participle. These forms still appear, especially where what’s bid (or bidden) is a hello or a goodbye, but they are fading from the language and may soon disappear. In today’s English, bid is usually uninflected.
But I do like Slippery's interpretation, and will most likely use that in future.
