Tips

grammar
The toneless 哇 is 啊 under phonetic assimilation: when the previous syllable ends in -u or -ao, the mouth is already rounded, so 啊 naturally picks up a w- glide and gets written as 哇. Compare 呀 after -i / -e / -ü, and 哪 after -n. Same particle, different spelling for each vowel environment.
usage
Sentence-final 哇 softens the tone (exclamation, emphasis, gentle command). Mid-sentence after a name or address, it marks a call-out: 老王哇 = "Hey Old Wang." The 1st-tone 哇 ("wow!" / cry / retch) is a completely different word - that one stands alone as an exclamation, this one always rides on the back of another syllable.

Components

radical
口 kǒu
mouth
Left-side 口 is the mouth radical - the standard marker for particles and exclamations that exist only in speech. The toneless particle family all wear it: 啊, 呀, 哪, 哇, 啦, 吗 - different vowel environments, same mouth-radical signature.
phonetic
圭 guī
jade tablet (here phonetic)
Right 圭 borrows its sound from the sister reading 哇. As a toneless particle the syllable drops its tone entirely - 圭 contributes nothing semantic. 哇 is a convenient phonetic spelling of the 啊 particle in its rounded-vowel allomorph.
