How do Buddhists express condolences?

Since converting to Buddhism, I've been unsure how to express condolences when people pass away. Everything familiar that I might say comes from a Christian perspective such as "being in a better place" or "with the Lord now". Simply letting the family know that I'm thinking of them works. But I'm wondering what is typical or traditional in Buddhist countries (or among experienced Buddhists in the west) where teachings of impermanence and rebirth may change the mindset regarding death. What is the typical way to express condolences among Buddhists?
