How to write your original (non-Chinese) and Chinese name, jointly
Your best source is 百度 百科 here's some examples of how they do it:

基努·里维斯（Keanu Reeves）
布兰妮·斯皮尔斯（Britney Spears）
奥兰多·布鲁姆（Orlando Bloom）

So the format here is: transliterated first name + · (interpunct code point U+00B7 · MIDDLE DOT) + transliterated surname + （ (General purpose
(fullwidth East-Asian) / U+FF08 Fullwidth left parenthesis) + ） (General purpose
(fullwidth East-Asian) / U+FF09 Fullwidth right parenthesis)
Also, you can see there is no space after the Chinese name and the left parenthesis.
Your name then would look something like this:
文森特·费尔海恩（Vincent Verheyen）
the reverse would also work for said purpose
Vincent Verheyen（文森特·费尔海恩）

Out of curiosity, here's also an example of a famous westerner with a Chinese name - with his Chinese name and then western-name on a &quot;single line&quot;
大山（本名马克·亨利·罗斯韦尔，Mark Henry Rowswell）
