boh(n) DJEE-ah. The second word starts with a "dj" like the beginning of "jeep," not a plain d.
Each word gets its own accent: "bom" is a single stressed syllable, and "dia" takes the weight on "di-" because words ending in -a are stressed on the second-to-last syllable by default, no written mark required. In the phrase as a whole, "dia" is the louder of the two.

"Bom dia! Como vai?" pairs the greeting with a stock question, and the linking is worth hearing: the nasal end of "bom" flows straight into the d of "dia" so the phrase has no gap in it. Meanwhile "vai" ends in the same "eye" diphthong shape you'll meet all over the language.
Almost every English speaker says "bom DEE-ah" with a hard d, which is the single most recognizable non-Brazilian accent marker there is. Make it "DJEE-ah." The other half of the problem is the m in "bom": English speakers close their lips and produce an audible "bome," when the m is purely a spelling instruction to nasalize the vowel.
