when talking to a male: teh-chah-yech. Hashem ohev otcha. (תחייך, ה׳ ×והב ×ותך)
when talking to a female: teh-chah-y'chi. Hashem ohev otach. (תחייך, ה׳ ×והב ×ותך)
(The "ch" is a gutteral sound. If you pronounce it like the ch in chew, you won't be understood).
It depends on whether you're talking to a man or a woman:
to a male: techa-yech, hashem ohev ot'cha (תחייך, ה׳ ×והב ×ותך)
to a female: techa-yeh-chi, hashem ohev otach (תחייכי, ה׳ ×והב ×ותך)
to smile again = lekhayekh od pa'am = לחייך עוד פעם

In Hebrew? In Biblical Hebrew it would be Elohenu Eloah ehadh. Or you could say the Shema which is Sh'ma Yisrael Adonai Elohenu Adonai Ehhadh.
God is with us = "ha shem imanu" (ה׳ ×¢×ž× ×•)
eved hashem (עבד ה׳), which also means "servant of God" (in Hebrew, there's no distinction between slave and servant).
